使用太多塑料袋对环境有害。3.Ifwedonothing,thesituationwillgetworse.如果我们什么都不做，情况会变得更糟。结构分析：这是一个主从复合句。主句是thesituationwillgetworse，其中thesituation作主语；willget作谓语；worse作表语。从句是由If引导的条件状语从句，we作主语；do作谓语；nothing作宾语。“If+从句，+主句.”表示“如果……，……就会……”。注意：在if引导的条件状语从句中，从句用一般现在时，主句用一般将来时，即遵循“主将从现”原则。e.g.Ifyoustudyhard,youwillgetgoodgrades.

如果你努力学习，你就会取得好成绩。Ifitrains,wewillstayathome.如果下雨，我们就会待在家里。Listentotheconversationandanswerthequestions.1.WhatisBrian’sideaaboutthegarbageonthebeach?2.WhydidJennysuggestaskingtheirfamilymemberstohelp?3.Howdotheyfeelaftercleaningupthebeach?Cleanupthebeach.Theyfeelproud.Becauseitwouldtaketoolongtocleanupthebeach.Brian:Howaboutcleaningupthebeach?Danny:Soundsgood.Butitwouldtaketoolong.Thereareonlythreeofus!Jenny:Wecanaskourfamilymemberstohelp.Brian:Goodidea!Theyexplaintheplantotheirfamilymembers,andeveryoneagreestohelp.Theyspendtherestoftheafternoonpickingupbottles,plasticbags,andallkindsofgarbageonthebeach.Beforeleaving,theytakeafinalswim.Theyfeelproudthattheymadeadifferenceatthebeach.打扫花费很长时间asksbtodosth要求某人做某事explainsthtosb向某人解释某事agreetodosth同意做某事agreeto…赞同；赞成agreeon…对……达成一致agreewithsb同意某人（的观点或意见）除余的，剩余的（连接主语，谓语由of后面的n.定单复数）捡起游了最后一次泳起作用Jenny,Danny,andBrianwereonabeachvacationwiththeirfamilies.Jennysteppedona____________.Dannysawamanleavinghisgarbageonthebeach.Theythoughtthesituationwould______________ifpeopledidnottakeactiontoprotectthebeach.Sotheydecidedto________________thebeach.Theyaskedtheirfamilymemberstohelp.Theyspenttheafternoon__________________allkindsofgarbageonthebeach.They_________________thattheymadeadifferenceinkeepingthebeachcleanandprotectingtheoceananditscreatures.beachgetworsecleanuppickingupfeltproudlivinghisgarbageisharmfultogetworsecleanupagreestotherestofpickingupmakeadifferenceTheythinksuchbehaviour___________theoceananditscreatures.Iftheydonothing,thesituationwill______________.Jennysteppedona______andDannyseesaman________________onthebeach.Theydecideto_________thebeachandexplaintheplantotheirfamilyme
